ABSTRACT:
A gas fuel supply control system for a plurality of poultry brooders arranged in a series and each having a gas fired main burner. The control system includes an electrically activated main gas regulating valve device electrically controlled by electrical signals from a thermostatic switch to open and close it at predetermined temperature levels, and regulate the gas fuel supply through a main burner manifold to all of the brooder main burners. A non-electrical self-operating hydraulic snap valve device having a temperature sensing fluid which directly effects valve opening and closing forms a bypass around the electrically activated regulating valve device and is set to operate at a slightly lower temperature to take over automatic control of the gas supply to the manifold during electrical power failure disabling the electrically activated valve.
